Abstract
The invention discloses a penetration type hot air drying furnace, which mainly consists of a left drying chamber, a heat exchange chamber, a right drying chamber, a furnace body, a heat exchange coiled tube type discharge flue and a hot air circulation fan. The hot air circulation fan pushes hot air to move downwards; the hot air is subjected to a first heat exchange through the heat exchange coiled tube type discharge flue and is subjected to a second heat exchange through the outer wall of the furnace body and the furnace body; the hot air passes through a hot air channel to enter the left drying chamber and the right drying chamber; the hot air penetrates through to-be-dried materials in the left drying chamber and the right drying chamber upwards and then flows back to the interior of the heat exchange chamber. According to the penetration type hot air drying furnace, a twice heat exchange form is utilized, the heat in the discharge flue is absorbed firstly, and the heat from the furnace body is absorbed secondly, so that the utilization ratio of the heat is largely increased; an automatic temperature controller is additionally arranged, so that the utilization ratio of the heat is further increased, and the energy source is economized.
Description
Technical field
The present invention relates to a kind of agricultural product processing machinery, specifically a kind of hot air drying stove.
Background technology
Blast funnace hot blast stove can be divided into heat accumulating type and heat exchange type two kinds by operation principle, regenerative hot blast stove, by the heat storage point pebble stove (being called for short ball stove) of hot-blast stove inside and the hot-blast stove of employing checker brick, top ignition can be divided into by combustion system, internal combustion type, external-burnings etc. are several, improve the key technology that hot air furnace hot air temperature is intensification of smelting process in BF.How to improve wind-warm syndrome, be the direction that insider studies for a long period of time.Conventional way is multifuel combustion high heating value gas, or increases the heat exchange area of stove fillings, or changes material, the density of checker brick, or changes the shape (as heat-storing sphere) of heat storage, and by various methodologies by coal gas and combustion air preheating.Heat accumulating type checker brick hot-blast stove is the most frequently used hot-blast stove form of current modern blast furnace, especially Large Scale BF.Advantage: heat-exchange temperature is high, heat utilization efficiency is high, work air quantity is large, is suitable for Large Scale BF need of production.Shortcoming: volume is large, floor space is large, and acquisition cost is high.Heat exchange type hot-blast stove, master uses high temperature resistant heat exchanger to be core component, these parts can not use metal material heat exchanger, refractory ceramics heat exchanger can only be used, blast furnace gas is Thorough combustion in combustion chamber, and the hot-air after burning, through heat exchanger, heat is given fresh cold air, fresh air temperature can be made to reach more than 1000 degree.Advantage: heat-exchange temperature is high, heat utilization efficiency is high, and volume is little, and acquisition cost is low.Preheating furnace is used to carry out the modern hot blast of combustion air preheating.Shortcoming: heat-exchange temperature is high less than heat accumulating type, uses scale less.
There is following defect in existing heat exchange type hot-blast stove: one is that heat exchange area is little, and heat utilization rate is low; Two is do not have automatic temperature to control, therefore wastes the energy.
Summary of the invention
The object of this invention is to provide the penetration hot air drying stove that a kind of heat utilization rate is high.
For achieving the above object, the technical solution adopted in the present invention is:
Penetration hot air drying stove, it is primarily of left drying chamber, heat-exchanging chamber, right drying chamber, body of heater, heat exchanger coil formula discharge flue and hot air circulation blower are formed, described left drying chamber and right drying chamber are located at the both sides of heat-exchanging chamber, left drying chamber is communicated with side bottom with the side roof part of heat-exchanging chamber, form a hot air circulation passage, right drying chamber is communicated with side bottom with the side roof part of heat-exchanging chamber, form a hot air circulation passage, described body of heater to be located in heat-exchanging chamber and and leave gap between the two side of heat-exchanging chamber and form hot-air channel, described heat exchanger coil formula discharge flue is located at the top of body of heater, the lower end of described heat exchanger coil formula discharge flue is communicated with the burner hearth in body of heater, the other end passes heat-exchanging chamber from the top of heat-exchanging chamber, described hot air circulation blower is located at the top of heat-exchanging chamber, hot air circulation blower promotes hot blast and moves down, first time heat exchange is carried out through heat exchanger coil formula discharge flue, second time heat exchange is carried out again through the outer wall of body of heater and body of heater, left drying chamber and right drying chamber is entered through hot-air channel, hot blast is upward through at left drying chamber and right drying chamber and is back in heat-exchanging chamber by after the material of drying.
Penetration hot air drying stove, also comprises air blast, and new wind is sent in described body of heater by described air blast.
Penetration hot air drying stove, also comprise temperature sensor and controller, described temperature sensor is located in heat-exchanging chamber, and controller receives the temperature information in the heat-exchanging chamber of temperature sensor transmission, and carries out switch control rule according to this temperature information to hot air circulation blower.
Materials vehicle is provided with in described left drying chamber or right drying chamber.
Multiple permeability type material frame distributed from down to up is provided with in described left drying chamber or right drying chamber.
Beneficial effect of the present invention: owing to have employed the form adopting secondary heat exchange, first the heat in discharge flue is absorbed, then the heat that body of heater sends is absorbed, thus substantially increase the utilization rate of heat energy; Add the attemperating unit of automation, thus further increase heat utilization rate, save the energy.
